Specification of Letters Patent.

Patented March 2, 1909.

Application filed November 29, 1907. Serial No. 404,364.

To all whom it may concern:

Be it known at l, Gnonen A. NoomvmN, a citizen of the United States, residing at Chicago, in the county of Qook and State of Illinois, have invented new and useful linprovements in Journal-Boxes, of w icli t e following is a specification.

This invention relates to improvements in journal boxes and more particularly to ti at type of journal boxes for car axles l; aving a lid wl-ich is made to swing edgewise.

The object of tie invention is to provide for folding the ed ewise swinging lid of a journal box securely in its open and closed positions and to close the lid automatically and tightly when it is released from open position.

A further object of t; e invention is to provide a journal box with an edgewise swinging lid wiiich is normally licld tightly closed against the box and is ringed thereto in a novel manner w" ereby the lid is caused to move outwardlv away from the box as the lid is opened and inwardly against t? e box as it is closed.

in the accompanying drawings Figure l is a front elevation of a journal box embodying my invention and sl owing tlie inge at t e right side of the box. Fig. 2 is a similar Fig. 3 is a view of tr e inner face of tl'. e lid upside down. Fig. 4 is a front elevation of a journal box sli owing the hinge at the top of the box. Fig. 5 is a view similar to Fig. 1 showing the lid in open position. Fig. 6 is a detail view showing the cams on the lid. Fig. 7 is a similar view showing the cams on the box. Fig. 8 is a sectional view on the line 88 of Fig. 1. Fig. 9 is a detail sectional view showing the position of the pintle reversed.

Referring to the drawings, 9 designates a journal box having an opening 10 generally rectangular in shape and surrounded by flat faced walls 11. The invention has relation more particularly to the lid and the manner of hinging the lid to the box and therefore it can be embodied in boxes of different constructions. For this reason I have shown the box in a more or less conventional form. A lug 12 projects outward from the box adjacent to one wall of the opening 10 and this lug is provided in its front face with two cam recesses 13 and 14 radially disposed on opposite sides of the pintle opening 15. In the construction shown in Fig. 2, in which the j lirge is located at one side of the box, the l big-:21 point 1.3 of the cam 13 is located above the pintle opening and ti e l igh point 14 of the cam 14 is located below ti e pintle opening and these ligh. points are made wide and flat for a purpose hereafter described. Between t le high point 14 of cam 14 and the low point 13 of cam 13 there is a flat section 16 and between t..e l igh point 13 of cam 13 and t e low point 14 of cam. 14 t ere is a similar flat section 16.

A lid 17 (Fig. 3) is made with a flat inner face to fit tightly against the flat faced walls 11 on the box and I may provide a flange 18 at the top of the lid on the inner face thereof to project over the wall at the top of the box. The lid is provided at one edge with a lu corresponding in location and general form to the lug 12 on the box and having a pintle opening This lug 19 is provided on its rear face with projecting cams and flat sections between the cams complementary to those on the box lug. The cam 20 is located at the left and the cam 21 at the right of the pintle opening and the high points 20 and 21 of these cams are made wide to correspond with the high points 13 and 14 of the cam recesses in the box. There are also flat sections 22 and 22 between and separating the cams 20 and 21 corresponding to the flat sections 16 and 16 on the box lug. Reference has been made to the particular location and arrangement of these cams to enable the invention to be more-readily understood and read on the drawings, but the invention does not depend upon this particular arrangement and it is important to the extent only that by the engagement of the shoulders 20 and 2 on the high points of the lid cams with the shoulders 18 and 14 on the high points of the cam recesses in the box a limit is provided to the closing swing of the lid so that the movement of the lid to closed position will stop with the lid properly centered over the opening in the box. A stop projection 23 on the lid lug may be provided to engage the box in or about the manner shown in Fig. 5 to limit the opening swing of the lid. A pintle 24 extends transversely through the openin 15 in the lid lug and the opening 15 in the ox lug and is provided with a head 24 which is preferably countersunk in the lid lug. (Fig. 8.) The end 24 of this pintle is threaded and projects some distance beyond the box lug 12. A spring 25 is arranged on the pintle with one end bearing against the box lug and the other end inclosed in a cup washer 26. This spring is held in place on the pintle and at pro er tension by a nut 27 on the threaded en of the pintle which bears against the washer 26 and by a cotter pin 28. The construction must be such that the lid shall be permitted an outward movement in a direction lengthwise of the pintle suflicient to permit the high points of the lid cams to travel up on the high points of cam recesses in the box, and the spring is therefore adjusted to pro er tension for this purpose and to hold the id securely in position when closed and when open. The lid is provided at its edge opposite the lug with a hook 29 or some other projection or device which can be engaged to open the lid.

While in general practice the hinge will probably be located almost universally at the right side of the box it will be apparent that ithout departing from my invention in any respects the hinge can be located at the left side, at the top or at the bottom of the box and the cams can be easily located in proper position wherever the lugs are arranged to ermit the lid to be opened in the manner cescribed and as far as may be desired,

When the lid is closed the high points of the cams will engage the flat sections and the spring holds the lid in this position tightly against the fiat faced walls surrounding the opening in the box and forming a close and dirt proof closure. As the lid is swung edgewise to open position the cams on the lid travel up on the cam recesses in the box until the high oints of the cams on the lid engage the hig oints of the cam recesses in the box, As t ese high points have some width and are fiat on their faces the lid will be held by the spring in open position until it is swung backward and the cams on the lid begin to travel down the cam recesses in the box. After the return movement is started it proceeds very quickly because the spring makes. the cams on the lid travel quickly down the cam recesses in the box to carry the lid into closed position. The outward movement of the lid, as it is opened, and the inward movement of the lid, as it is closed, occur during the edgewise movement of the lid.

I refer to arrange the pintle with the head at t e front of the lid as shown in Fig. 8 but this arrangement may be reversed, as shown in Fig. 9, and the same result produced.

While I have shown the pintle secured in the lugs and the spring held in place by a nut, a washer and a cotter pin on the intle, it will be apparent that any other 'astening means suitable for the purpose may be employed without departing from my invention.

What I claim and desire to secure by Letters Patent is:

The combination of a journal box for car axles having an opening therein, a lid hinged to said box and movable edgewise over said opening, said box and lid having lugs thereon located opposite each other, there being cam recesses in the front face of the box lug separated from each other and projectin cams on the rear face of the lid lug separate from each other and adapted to travel in the cam recesses in the box lug, a pintle arranged in said lugs to hinge the lid to the box, and a spring on said pintle for holding the cam faces, of said lugs in engagement.
